What is Amazon Pay Per Click — and Why It's More Than Just Advertising?
Amazon Pay Per Click (PPC) is Amazon's advertising system where you only pay when someone clicks on your ad. You bid on keywords or products, your ad appears in search results or on product detail pages — and the cost per click is determined by the market and competing bidders.
That sounds straightforward, but it has a strategic depth that many underestimate. Amazon PPC doesn't just influence your direct advertising sales. Every sale you generate through sponsored ads signals to Amazon that your product is relevant and in demand. Over time, this improves your organic ranking — the position you hold without active advertising.
Three metrics sit at the heart of this: ACoS (Advertising Cost of Sales) shows what percentage of your advertising revenue goes on ads. TACoS (Total ACoS) sets your ad spend against your total revenue — including organic sales. ROAS (Return on Ad Spend) is the inverse of ACoS and shows how much revenue you generate for every pound spent on advertising.
- ACoS = Ad spend ÷ Ad revenue × 100
- TACoS = Ad spend ÷ Total revenue × 100
- ROAS = Ad revenue ÷ Ad spend
The Three Ad Formats: Sponsored Products, Brands and Display
Amazon offers three different ad types. Each has its own purpose — and the most common mistake new sellers make is launching all three simultaneously before any one of them is working properly.
Sponsored Products are the most accessible format. They appear directly in search results and on product detail pages, look like organic listings and therefore convert particularly well. No brand protection required, ready to use immediately. For any seller just starting out, Sponsored Products are the only sensible first step.
Sponsored Brands require a registered trademark (Amazon Brand Registry). They appear prominently above search results, displaying your logo, a custom headline and up to three products. Effective when you're marketing several products under one brand and want to build brand awareness.
Sponsored Display goes a step further: these ads reach users outside of Amazon too — on other websites and apps. The format is suited to retargeting, targeting users who have already viewed your product or similar products but haven't purchased. CPM is often lower here than CPC on Sponsored Products, but conversion rates are naturally lower as well.
- Sponsored Products: No brand protection required, bookable immediately, ideal for getting started
- Sponsored Brands: Requires Brand Registry, strengthens brand presence in search results
- Sponsored Display: Retargeting function, works outside Amazon too, well suited to the consideration phase
Automatic vs. Manual Campaigns: What You Actually Need
Amazon distinguishes between automatic and manual campaigns. The difference is fundamental and determines how much control you have over targeting, budget and results.
Automatic campaigns leave the decision to Amazon — which search terms and product pages your ad appears on. Amazon draws on information from your listing: title, bullet points, back-end keywords. Useful for getting started and gathering data, but expensive over time if you don't actively adjust.
Manual campaigns give you full control: you choose keywords or ASINs, set bids and use match types to determine how broad or narrow your targeting is. It takes more time, but delivers better results once you know which keywords actually convert.
The tried-and-tested strategy: start with an automatic campaign on a low daily budget — £15 to £20 is sufficient. After two to three weeks, analyse the Search Term Report and identify which search terms led to purchases. Transfer these as Exact Match keywords into a manual campaign. Terms that generated clicks but no purchases go onto the negative keyword list.
Keyword Targeting: How to Use Broad, Phrase and Exact Match Correctly
In manual campaigns, there are three match types that determine how narrowly or broadly Amazon serves your ad. Each has a different purpose — and mixing them up leads to losing track of costs and performance.
Broad Match is the widest type. Amazon serves your ad for related search terms, synonyms and phrases containing your keyword. Advantage: high impression volume and reach. Disadvantage: often irrelevant traffic. Example: the keyword 'dog lead' might appear for 'cat harness with lead'. Use Broad Match to discover new search terms — not as your main strategy.
Phrase Match narrows things down: your keyword must appear as a continuous phrase within the search query but can be surrounded by other words. 'Long dog lead' would match 'red long dog lead reflective' but not 'long lead for dogs'. A good middle ground between reach and relevance.
Exact Match is the most precise type. Your ad only appears when the search query matches your keyword exactly — with minor variations such as singular and plural allowed. This produces low volume but very targeted traffic with the highest conversion rates. This is where you set your highest bids.
Practical recommendation: use Broad Match in the automatic campaign or an exploratory manual ad group. Phrase Match for proven topic areas with moderate volume. Exact Match for your confirmed top converters — with full bid control.
- Broad Match: Maximum reach, low precision — good for keyword discovery
- Phrase Match: Balanced reach, keyword must be present in the search query
- Exact Match: Minimum reach, maximum relevance — best conversion rate, highest bids
Bidding Strategies and Budget Planning: How to Control Your Spend
Amazon offers three bidding strategies for Sponsored Products. Your choice directly influences how aggressively Amazon bids on your behalf — and therefore how stable your ACoS remains.
Dynamic bids — down only: Amazon automatically lowers your maximum bid when a conversion seems unlikely. This protects your budget but can mean you miss out at critical moments. Recommended for campaigns with tight budgets or during the scaling phase.
Dynamic bids — up and down: Amazon can increase your bid by up to 100% when a conversion appears likely. This maximises opportunities but pushes ACoS up. Makes sense when your break-even ACoS leaves enough room to manoeuvre.
Fixed bids: Amazon always bids exactly your set amount — no adjustments up or down. This gives you the most control and is ideal for systematic tests where you want to minimise external variables.
On budget planning: don't start too lean. A daily budget under £15 is barely enough for statistically meaningful data, especially in competitive categories. Allow at least 30 to 45 days before evaluating or restructuring campaigns. Spread your budget across two to three campaigns rather than putting everything into one — you'll learn what works much faster.
- Minimum daily budget for usable data: £15–£25 per campaign
- Test phase: at least 30 days before making fundamental decisions
- Rule of thumb: budget 10% of your monthly revenue target for PPC
Optimising ACoS and TACoS: From Raw Data to Decisions
ACoS is the central metric in Amazon PPC — but there is no universally good ACoS. The right target depends on your margin, your strategy and the stage your product is at.
In the launch phase, a high ACoS is acceptable — sometimes even strategically necessary. You are buying visibility and sales history. Running a new product at 60–80% ACoS and making a short-term loss can be the right call — if you are investing in rankings and they are measurably growing.
In the optimisation phase, bring it down gradually: increase bids for keywords converting below break-even ACoS. Lower or pause keywords with high ACoS and no conversions. Review the Search Term Report at least once a week and continuously add new negative keywords.
TACoS is your most honest measuring instrument. When your TACoS falls whilst your total revenue stays stable or grows, your organic ranking is improving — that is the real goal of any long-term PPC strategy. A falling TACoS alongside a stable ACoS means your advertising is building organic strength.
Concrete optimisation rules: keywords with more than 15 clicks and zero conversions are candidates for a bid reduction of 20–30% or negation. Keywords with an ACoS below break-even and at least 3 conversions deserve a bid increase of 10–15%. Make both adjustments every two weeks — not daily.
- Weekly: review Search Term Report, add negative keywords
- Every 2 weeks: adjust bids (+10–15% for performers, −20–30% for cost drivers)
- Monthly: review campaign structure, shift budget towards top performers
The Most Common PPC Mistakes — and How to Avoid Them from the Start
Most sellers lose money on Amazon PPC not because of poor products, but because of avoidable structural errors in campaign management.
Mistake 1: Too many keywords in one ad group. Putting 150 keywords into a single ad group means losing oversight and being unable to set differentiated bids. A maximum of 20 to 30 keywords per ad group is a workable limit — grouped by topic or match type.
Mistake 2: No negative keywords. If you never exclude search terms, you continuously pay for irrelevant traffic. Within the first week, you should already be pulling negatives from the Search Term Report. This is often the quickest way to lower your ACoS.
Mistake 3: Pausing campaigns too early or intervening too late. PPC needs data — but waiting too long costs money. Give campaigns 2 to 3 weeks for an initial assessment. After that, decide based on data, not gut feeling.
Mistake 4: Looking at your listing and PPC in isolation. Your product listing is the landing page for your ads. Poor main images, a weak title and missing keywords in the listing mean low conversion rates — regardless of how much you bid. Always optimise your listing and campaigns in step with each other.
Mistake 5: Staring solely at ACoS. ACoS shows advertising efficiency. TACoS shows overall effectiveness. If you only look at ACoS, you won't see whether your advertising is building organic ranking strength or draining it.
Frequently Asked Questions
What is a good ACoS on Amazon PPC?
It depends on your product margin. Your break-even ACoS = (Selling price − COGS) ÷ Selling price × 100. With a 40% margin, anything below 40% ACoS is profitable. In the launch phase, a higher ACoS can make sense if you are deliberately investing in building rankings.
How much budget do I need for Amazon PPC?
As a rule of thumb: budget around 10% of your revenue target for PPC. For meaningful test campaigns, you need at least £15 to £25 daily budget per campaign. Less produces too few clicks for reliable optimisation decisions.
What is the difference between automatic and manual Amazon campaigns?
With automatic campaigns, Amazon decides which keywords your ad appears for — good for gathering data. With manual campaigns, you choose the keywords, match types and bids yourself. Running both in parallel is the recommended strategy for growth.
When will I see first results from Amazon PPC?
You'll see first clicks and impressions within hours of launching. Actionable data for optimisation decisions is available after 2 to 3 weeks. Measurable ranking improvements typically emerge after 4 to 8 weeks of consistent campaign management.
What are negative keywords and why do they matter?
Negative keywords exclude search terms where you don't want your ad to appear. If you sell women's shoes, you don't want to show up for 'men's shoes'. Consistently adding negatives is often the fastest way to lower your ACoS — without changing a single bid.
Do I need Amazon Brand Registry for PPC advertising?
Not for Sponsored Products — these are accessible to all sellers without restriction. Brand Registry is required for Sponsored Brands. Sponsored Display is also only available to registered brand owners and Vendor partners.
